COIN-CONTROLLED LOCK.

Application led March 1, 1920. Serial No. 362,308.

To @ZZ toLof/n t lmay concern.'

Be it known that l, CHARLES El. VAN Cinnvn, a citizen of the UnitedStates, residing at Indianapolist in the county ot Marion and State otIndiana7 have invented certain new and useful improvements inCoin-Controlled Looks, et which the 'following is a specification.

This invention relates to coin controlled locks intended for any purposewhich requires a coin to operate a lock and is often employed in publictoilets. lockers, baggage receptacles, ete., wherein a locked door isopened by means of a coin. The present invention has among its objectsthe making of an improved lock which is simple in construction, reliablein operatiom and consists t but iew parts.

ln ycarrying the objects ot my invention into eti-ect7 l provide a coinoperated lool; which is arranged so that upon inserting the proper coinfrom the outside a connection is formed which allows the backwardmovement or" -the bolt on turning the outside knob, at the same timeclosing the coin slot and unlocking the door. iFor example in the caseof a toilet door, when the operator enters the roon and closes the doorbehindv him the coin drops into the coin box and lor-.ks the door which'can be opened only from the inside by the occupant ot the room. llhenhe leaves the room turning the inside lniob the coin slot uncoveredputting` the mechanism in operative position again.

Reterring to the accompanying drawings torming a part hereof and inwhich similar ence characters denote similar parts,

F igure l, illustrates a front yview ot the lock with the cover and coinbox lcut away and taken on the line l-l ot Figure 2, and.

Figure 2, a transverse section taken along line 2N2 of Figure l.

The casing l of the lock has a coin slot 2 in the upper portion thereofcommunicating with a slotted projection formed on the rear portion oircover 33, and constitut ing a coin guide. A bolt Il, having a projection5 and rear extensions (i and 7, the extension 7 being litted with spring8 to hold bolt 4 in closing position, is secured to the easing by guides9 and 10.

A stop 1l is 'formed on extension 6 and in proximity thereto is a shaftmember l2 having an angular extension .i3 upon which is fitted a knoblet forming the interior operating` handle. Fixed to the inner end ofmember l2 is a projection l5 adapted to contact with stop 1li. andhaving at its upper end a projection 16. coin slot cover l? is journaledin the casing at 18 and has a downwardly extending projection lf)adapted to be engaged by projection 1G and a coin. A forked member 2O issecured to the coin slot cover and engages a pin 2l iixedjto counter 22adapted to record the number ot times the lock has been operated.

A shaft 23 is journaled in the casing and has an angular extension 24with a knob 25 fixed thereto forming the exterior operating handle ofthe lock. Fixed to this inember is a projection 2G having a stop member2? adapted to engage a projecting stop 2S termed on the casing. Ahorizontal stop 29 is 'formed on the easing at a point directly belowportion 5 of the bolt which termed with a coin slot 30 for the receptionof a coin 3l. rthe relativo sizes of projection 29 and coin slot 30 aresuch that when the proper coin is inserted it will be held in place bymembers 29 and 3() with the upper portion of the coin extending inproximity to member 19 and the lower portion to member 26. A coinsmaller than the proper size will not be engaged by members 29 and 30and will drop into the coin box without operating the lock. A coin toolarge cannot be inserted into coin slot 2. A projection 32 is termed onthe upper end oi? the rear section 3?) and has a hollow portion which isadapted to engage a tongue is formed on the front part oi" cnsing l tohold the parts oil? the casing together. n

The operation oit the lock is as follows:

In locked position the relative positions ot' the parts are as shown inthe drawings. coin is inserted in slot 2 and assumes the position shownin Figure l. This forms connections between stop member 26, the lowerportion of the coin7 the bolt 4t and projection 19 oit coin slot cover17. Upon turning the knob of exterior operating handle 25 the bolt 4 isshot back and coin slot cover 17 is pushed so as to cover coin slot 2.This allows the toilet door A to be opened and the operator to enter theroom whereupon, in closing the door7 bolt 4 is again shot back bycontacting with the fixed portion of the latch thereby throwing coin 31down into the coin box (not shown).

Vhen the occupant leaves the room he turns interior operating handle 14causing projection 15 to engage stop 11 thus drawino: back bolt 4 andcausing stop 16 to engage with projection 19 uncovering the coin slot 2.As he closes the door behind him the door is locked and the mechanism isready for the next occupant. A key 35 is provided so that it may beinserted by an attendant and the lock opened without the use oi' acoinby engaging stop 16 and pushing it forward causingibolt 4 to be shotback.

Having thus fully described my said invention, what l claim as new anddesire to secure by Letters Patent, is:

1. A lock for doors and the like comprising a casing having a slot for acoin, a bolt having a slot to receive and hold said coin, a pivotedclosure tor the slot in the casing, sad coin adapted to contact withsaid closure, and means acting through the coin in the slot of said boltto retract the bolt and to close the slot in the casing, substantiallyas set forth.

2. A lock for doors and the like comprising a casing having a slot for acoin, a bolt having a slot to receive and hold said coin, a pvotedclosure ttor the slot in the casing, said coin adapted to contact withsaid closure, a counting device in said casing, a pivotal connectionbetween said counting device and said closure, and means acting throughthe coin in the slot of said bolt to retract the bolt to close the slotin the casing and to operate said counting means, substantially as setforth.

3. A coin controlled lock comprising a casing, a bolt. an interioroperating handle connected thereto. an exterior operating handle inproximity thereto, a coin slot, means ior making connection between saidexterior handle and said bolt through a coin, means operated by saidcoin lior closing said coin slot comprising a pivoted coin slot cover insaid casing having a projection thereon said coin being adapted toengage said projection, and means on said lirst handle also adapted toengage projection on said coin slot cover for uncovering said coin slot,substantially as set forth.

L1. )i coin controlled lock comprisng a casing, a bolt, an interioroperating handle connected thereto, an exterior operating handle inproximity thereto, a coin slot in said casing. a corresponding coin slotin said bolt transversely thereof, a projection on said casingco-operating with said second slot to hold a coin therein, a projectionlxed to said exterior handle adapted to en gage the lower portion ofsaid coin for oplerating said bolt, a pivoted coin slot cover,

a projection thereon adapted to engage the upper porton of said coin forclosing said coin slot. and means on said interior handle adapted toengage said projection for uncovering said coin slot, substantially asset forth.

5. ln a lock, a casing having a coin-slot, a bolt, coin-controlledmeans: to retract the bolt operable from the outer? side of the door, apivoted coin slot cover, a rock shaft, a rock arm thereon engaging thebolt, a second rock arzn on said rock shaft adapted to retract thecover, and means at the inner side otI the door whereby the rock sh a'ftmay be operated to retract the bolt said second rock arm being actuatedby a key for turning the rock shaft to retract the bolt, substantiallyas set forth.

6. In a lock, a Acasing having a coin slot, a bolt having a transverseslot for passage of a coin, an exterior handle, a rock shaft thereforhaving an arm to bear against the coin. a ledge adjacent the. boltadapted to hold in the slot only coins of a predetermined size andhaving a stop forming a guide for the coin, and an arm on said rockshaft arranged to abut against said stop to limit the movement or' therock shaft, substantially as set Jforth.

ln witness whereof, l have hereunto set my hand at indianapolis,Indiana, this 24th day oit February, A. D. nineteen hundred and twenty.
